Abstract EN

The intersection collision warning system (ICWS) is an emerging technology designed to assist drivers in avoiding collisions at intersections.

ICWS has an excellent performance in reducing the number of collisions and improving driving safety.

Previous studies demonstrated that when visibility was low under fog conditions, ICWS could help drivers timely detect hazardous conflicting vehicles.

However, the influences of ICWS on interactive driving behavior at unsignalized intersection between different vehicles have barely been discussed.

This study aimed to investigate the patterns of drivers’ interactive behaviors with the assistance of a new kind of ICWS under fog conditions based on Multiuser Driving Simulation.

The Multiuser Driving Simulation allowed multiple drivers to operate in the same simulation scenario at the same time, and it could capture drivers’ interactions preferably.

Forty-eight licensed drivers completed the driving simulation experiment in three fog conditions (no fog, light fog, and heavy fog) and two warning conditions (warning and no warning), in which the drivers drove in a straight-moving situation at unsignalized intersection with potential collision risks caused by the encounter of two vehicles.

The results verified that warning and fog conditions were significant factors that affected the interactive driving behavior in the unsignalized intersection collision avoidance process, including the driver’s decision, TTC of action point, average acceleration (deceleration) rate, and postencroachment time.

Compared to conditions without ICWS, the ICWS could help drivers make collision avoidance actions earlier and change the speed more smoothly.

In addition, with the help of Multiuser Driving Simulation, associations between decision driving behaviors of vehicles were discussed with caution.

The results revealed the decision-making mechanism of drivers in the process of interaction with other drivers.

Under the influence of fog, interactive driving processes were fraught with increased risk at unsignalized intersection.

However, the ICWS helped drivers interact more harmoniously, safely, and efficiently.

The findings shed some light on the further development of ICWS and the study on interactive driving behavior.
